This is the third multiple-murder this week that has garnered national attention.

Zina Haughton acquired a 4-year restraining order against her violently jealously husband, Radcliffe Haughton, 45, on Thursday. Sunday morning, he murdered her and two other women at the Azana Day Spa in Brookfield, Wisconsin where she worked.

As previously reported by NewsOne, Zina wrote in the restraining order, “His threats terrorize my every waking moment.”

Haughton was discovered in the back of the spa with a fatal self-inflicted gunshot wound.

Also on Sunday,Desmond John Moses, 55, of Inglewood, California, is suspected of setting fire to his neighbor’s home before killing him and his 4-year-old son, and critically injuring the child’s mother and siblings. Moses was later found dead in his home, which it is also suspected that he set on fire, wearing bullet-resistant armor. He had a hole in the head from his .38 caliber weapon. Because his body was burned beyond recognition, police initially had to wait on autopsy results to confirm that it was him.
